A ROSAT survey of Hickson's compact galaxy groups [PDF]
, 1996 We report the results of an almost complete survey of the X-ray properties of Hickson's compact galaxy groups with the ROSAT PSPC. Diffuse X-ray emission is detected from 22 groups.

Advanced Science, EarlyView.In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

No Evidence of Asymmetrically Enhanced Star Formation in Infalling Galaxies in UNIONS
The Astrophysical JournalRam pressure stripping is a well-known environmental quenching mechanism that removes gas from galaxies infalling into groups and clusters. In some extreme examples of ram pressure stripping, galaxies with extended gas tails show evidence of enhanced ...

Galaxy Groups as the Ultimate Probe of AGN Feedback
GalaxiesThe co-evolution between supermassive black holes and their environment is most directly traced by the hot atmospheres of dark matter halos. The cooling of the hot atmosphere supplies the central regions with fresh gas, igniting active galactic nuclei ...

A derivation of masses and total luminosities of galaxy groups and clusters in the maxBCG catalogue [PDF]
, 2015 We report the results of a multi-waveband analysis of the masses and luminosities of $\sim$600 galaxy groups and clusters identified in the maxBCG catalogue.

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields
Advanced Science, EarlyView.Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Tracing the Formation History of Intrahalo Light with Horizon Run 5
The Astrophysical JournalWe investigate the formation history of intrahalo light (IHL) using the high-resolution (∼1 kpc), large-scale (∼1 Gpc) cosmological hydrodynamical simulation Horizon Run 5 (HR5).

Galaxy And Mass Assembly (GAMA): the halo mass of galaxy groups from maximum-likelihood weak lensing [PDF]
, 2014 We present a maximum-likelihood weak-lensing analysis of the mass distribution in optically selected spectroscopic Galaxy Groups (G3Cv5) in the Galaxy And Mass Assembly (GAMA) survey, using background Sloan Digital Sky Survey (SDSS) photometric galaxies.

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas
Advanced Science, EarlyView.To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).

The Metal Content of the Hot Atmospheres of Galaxy Groups
Universe, 2021 Galaxy groups host the majority of matter and more than half of all the galaxies in the Universe. Their hot (107 K), X-ray emitting intra-group medium (IGrM) reveals emission lines typical of many elements synthesized by stars and supernovae.
